Manages Craft and plugin migrations.

A migration means a set of persistent changes to the application environment that is shared among different developers. For example, in an application backed by a database, a migration may refer to a set of changes to the database, such as creating a new table, adding a new table column. This controller provides support for tracking the migration history, updating migrations, and creating new migration skeleton files. The migration history is stored in a database table named migrations. The table will be automatically created the first time this controller is executed, if it does not exist. Below are some common usages of this command:

# creates a new migration named 'create_user_table' for a plugin with the handle pluginHandle.
craft migrate/create create_user_table --plugin=pluginHandle
# applies ALL new migrations for a plugin with the handle pluginHandle
craft migrate up --plugin=pluginHandle
